HE ATING-EAPPLIANCE Specification of Letters Patent.

Application filed May 13, 1908.

Patented Nov. 24:, 1908.

Serial No. 432,621.

To all whom it may concern.

Be it known that I, VILLIAH B. BRIND, a citizen of the United States, residing in Paterson, lassaic county, New Jersey, have invented a certain new and useful Improvement in Heating Appliances; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters of reference marked thereon, which form a part of this specification.

This invention relates to steam or hot water heating apparatus and it has for its object to provide a steam or hot water heater which shall be comparatively inexpensive in construction, offer a neat and attractive appearance so that it may be set up and used directly in the apartment or apartments which it is designed to heat, be capable of being taken apart to facilitate moving it from place to place and adapted, at such times, to withstand rough handling and be so constructed that an ordinary gas outlet will be sufficient to sustain a flame which shall be ample, as the source of heat for the apparatus, to produce therefrom great heating capacity.

My invention is fully illustrated in the accompanying drawing, wherein,

Figure 1 is a side View thereof; Fig. 2 is a substantially central vertical sectional view; and, Fig. 8 is a fragmentary plan view of the lower portion of the apparatus, certain pipes or tubes appearing in horizontal section.

In the drawings, a designates a cylinder having its upper and lower ends closed by the heads 6 and a, which are held in proper disposition by means of the bolts (Z, suitable packing 6 being introduced at the joints between the cylinder and the heads so as to prevent leakage under pressure.

Through the cylinder extends vertically a central flue f whose ends are suitably fitted into the heads 6 and 0 so as to form tight joints therewith.

g is a dome comprising the (preferably) flat lower wall 71. and the concavo-convex upper wall 2', the two being secured together by the bolts j or the like with packing interposed between their edge-portions, as at This dome and the chamber formed by the cylinder and its heads are connected by the vertical tubes Z which are arranged in concentric series about the vertical space m, into which space the upper end of the fine f discharges; tight joints are formed between the dome, the tubes and the head 7) of the chamber referred to in any suitable manner. The chamber referred to is a water chamber and connected with the cylinder at are a water gage a and a filling and emptying attachment 0, the same comprising the vertical branch 1), having the valve Q and a filling funnel r, and a horizontal branch 8 inwing a valve 25 and adapted, when such horizontal branch is not directly connected with a water supply, to be closed by the cap a; it will also be understood that this cap may be removed for the purpose of emptying. The dome has the pressure gage o, the safety valve w and the air release :0 attached to its' top wall 2'.

The structure comprising the water chamber, the tubes and the dome is adapted to rest on the flat ring y forming the top of a base 2 comprising the legs 1 having ballcasters 2 and the inwardly projecting arms 3 formed integrally therewith. These arms are adapted to support a removable Bunsen burner 4:

having the valved supply attachment 5 to which a rubber hose or the like may be connected. The construction of the boiler structure comprising the water chambe1',the tubes and the dome is such that when it is removed from the base 2 it may be packed, for shipping, in a limited space, and at such times will be reinforced against rough handling by the fact that its dome and water chamber project laterally outside of the tubes, while its removability from the base makes it possible to move the apparatus more conveniently from one place to another whenever this is necessary. \V hen in position on the base the projecting lower ends of the bolts limit the lateral movement of the boiler structure on the base so that it will not slide off the base when, as in cleaning the apartment, it is necessary to move the apparatus on the casters.

In operation, the parts being assembled as shown in the drawing, and water being placed in the water chamber to about the level marked 6, steam will be generated and circulate through the tubes Z in the direction of the arrows. The products of combustion from the burner pass up through the flue f 'lOO lltl

and into the space m, where they finally impinge against the lower flat wall it of the dome and rebound, finding their way out through the concentric series of tubes; some of the products of combustion of course pass out through the tubes in the lower portions thereof, so that, on the whole, there is a general superheating of the tubes from top to bottom. This, taken with the direct heating of the water in the water chamber from the subjacent burner and the fact that the products of combustion are carried practically up through the body of water in the Water chamber, gives the apparatus great heating capacity. Substantially the whole of the structure comprising the water-chamber, the tubes and dome is rendered available for radiation because the circulation therein is maintained, the steam (or water) rising in the inner row or circle of tubes, owing to the greater heat there, and falling in the outer row, as indicated by the arrows.

t will be understood that the operation is substantially the same where the apparatus is used as a hot'water heater, in which instance the entire appartus is filled with water.

In order to impart an ornamental finish to the apparatus, the ornamented or plain rounded rings 7 and 8 may be placed over the joints between the parts of the dome and over the joint between the cylinder and top of the water chamber.

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent is:

The combination, in a heating apparatus, 01"" a base having its top portion formed as a flat ring, and a boiler structure comprising a water-chamber, a dome and a series of tubes connecting the dome and the water-chamber, said dome and the water-chamber having their marginal portions projecting laterally outside of the tubes, and said water-chamber comprising upper and lower disk-shaped heads, a cylinder interposed between said heads and bolts securing the heads and cylinder together and projecting below the lower head, said boiler structure being removably seated on the ring-portion of the base and having the bolts of its water-chamber projecting down into the ring and coacting therewith to limit the movement of the boiler structure laterally on the base, substantially as described.

in testimony, that I claim the foregoing, I have hereunto set my hand this 12th day of Blay, 1908.
